CATT-Acoustic v9.1

• 32-bit Windows MDI application for Windows XP..10 with four modules and direct link to CATT TUCT™ that handles all prediction and auralization (see overview). The software is based on geometrical acoustics (GA) with som extensions. The programs are 32-bit but run well under 64-bit Windows versions:

• modeling
  
• directivity
• surface properties
• PL9-file viewing/WAV-file playing

• CATT 3D-viewer based on OpenGL
• CATT PL9-viewer (a vector graphics file format offering animation and interactivity). A stand-alone viewer to complement the built-in viewer,
• The full auralization version also includes:
• CATT-Walker™ for real time walktrough auralization
• WalkDecim for walktrough convolution path decimations
• The FIReverb Suite™
• ReflPhinder™
• GratisVolver Pro™
• a customized text editor communicating with the main application
• a range of external tools for file format conversions, DXF import, walktrough tracks, and similar.
  
• comprehensive PDF manuals
• context sensitive help
• v9.1 is the 8th major update for Windows (v6.0 June 1996 (16-bit), v6.1 March 1997 (16-bit), v7.0 Feb 1998, v7.1 Oct 1998, v7.2 Oct 1999, v8.0 Feb 2002) and a range of significant v8.0 updates have been released since 2002, v9.0 June 2011, v9.1 January 2016). The new CATT TUCT™ was released in March 2010 see overview).
• comprehensive demo version is available

• CATT is an acronym for Computer Aided Theater Technique since theater lighting and decor CAD programs were the first CATT products in 1986. Since 1988, CATT has concentrated on software for acoustics prediction/auralization (CATT-Acoustic) and FIR reverberation tools (The FIReverb Suite™) and a B-format reflection analysis tool (ReflPhinder™)
• In a JASA paper ("Acoustic, acoustics", Robert T. Beyer, JASA 98(1), July 1995) the historical origins of the words acoustic and acoustics were researched. A reference from the 17th century was presented where the word "Catacoustics" was used to describe reflected sound (direct sound was called "Acoustics", and refracted sound was called "Diacoustics"). This makes the name CATT-Acoustic have some meaningful acoustical background since, in deed, reflected sound is exactly what it is about. This is of course pure coincidence since the software was named in 1988.
